So I just bought the rockler separator kit on sale and a new 30 gal fiber drum. I want it to be as efficient as possible so I thought I’d ask here. I know the thein lid is highly touted. I was thinking about trying to place the components in the lid like the thein and see how it does without the baffle underneath. Has anyone done this with success? I figured if it didn’t work I could always add the baffle. Or should I just put them in the lid like Rockler says to (each part on opposite sides opposed to one in the middle like the thein)

I appreciate any suggestions

or this one:

here are the conclusions the wood whisperer came to :

FWIW, i’ve seen several threads on phil’s site where other commercially available separator lids were used atop pails but with the baffle applied to the separator lid. in almost every case, inclusion of the baffle under the commercially avaialble separator lid improved the overall performance of the separator.

if you just got the components (first link above), build in the baffle. you’ll be glad you did.

The kit, since you already bought it will work adequately.

If you wanted the most efficient separation of dust and air, you wasted the money for the kit.
The Thein Baffle would be more efficient than any of the lids I have seen. Note: I do not know which kit you bought, but I am assuming the “Vortex Lid”.

The best separation will be had by inputting the air/dust stream tangent to the outer edge of the container and extracting the air flow up through the center. Also, the center tube should extend into the container to a point below the lowest point of the input. Without the baffle what you loose is about half the volume capacity of the container. In other words, when the container gets half full the spinning flow will re-entrain the lighter dust and carry it out the discharge with the air.

A cyclone shaped separator with the bottom (small end) of the cone sealed to the center of the container’s lid is the very best if it is sized properly. The spinning air flow does not get into the container very much at all and therefore does not get a chance to pick the dropped dust back up.

So, the efficiency rating of the various systems out there, from best to worst, would be #1. Cyclone sitting on top of a dust container. #2. Thein Baffle sitting on top of a dust container. #3. Home made separator lid with tangent inlet and centered outlet. #4. Purchased separator lids with 180 degree opposed inlet and outlet. #5. A simple drop out box with a center baffle between inlet and outlet.

The one I bought is just the components, not the lid. It was like 15 bucks. Looks like I need to do the baffle!

SAWEDOFF I have the same fittings installed in a small shipping drum and it works OK. I did have it set up with the Rockler Wall mount DC but have since replaced the Rockler DC with a HARBOR FREIGHT DC and added a cartridge filter. I plan in the future to build a THEIN separator.
